Electric fence
That's the funniest story I've heard!!! Reminds of time back several years ago when we were young and dense. There was an old wide spot back on an even older country road that we used to hang out at and drink a few cold ones. One night we all met up for a few cold brews like usual. Later in the night one of our friends got the urge to relieve his self over in the woods. Little did we know but there was an electric fence over in the edge of the field. Suddenly we here this WOOO WOOOO WOOOO coming from our friends vicinity. He comes running full speed back to the group, pants to his knees. He pissed on the fence and got a damn good jolt. It was hilarious!!! Till this day his nickname is freight train! ROFL!
